Upon pipeline implementation, hierarchical clustering identified three groups: groups 0, 1 and 2 hosted 39, 10 and 6 patients respectively.
In Fig. REF  the curves of the heights of the trees' vertices over the three groups can be appreciated: branches present different average heights according to the group their dendrograms belong (see Fig. REF ). Groups are shown to entail different heterogeneity extent, following an ANOVA functional approach [1]} [2]}.
